The Dosing Dilemma With CBD. How to dose CBD is a common question among practitioners. Indeed, preclinical and clinical research indicates an extremely wide range of doses that have been used. Although we are far from knowing what doses are ideal, taking into account pharmacogenomic variance among individuals is critical. Studies often refer to high-dose and low-dose CBD, although a review of the literature indicates considerable variability in how these are defined. For example, Zhornitsky and Potvin defined high-dose oral CBD as 150-600 mg/day.
